METHOD OF APPLYING BOTTLE-SEALS.

Specification of Letters Patent.

Patented June 11, 1907.

Application filed October 4, 1906. Serial No. 337,477.

To all whom it may concern.- Be it known that I, EDWARD D. SGHMITT, a citizen of the United States, residing at Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Methods of Applying Bottle-Seals, of which the following is a specification.

This invention relates to a method plying bottle seals.

A machine by which the method may be practiced is shown and described in my application filed October 20, 1906, Serial No. 339,812.

The invention contemplates the provision of the method of applying hard metal flange caps containing a compressible sealing member such as a cork disk, to a bottle having an annular laterally extending bead adjacent to its mouth, and wherein sealing contact. is made between the cork disk within the cap and the upper edge of the bottle, after which the flange of a cap is forced into locking engagplment with the locking surface of the In seals of this type now in use, the entire sealing pressure is placed upon the cork or compressible sealin ,disk forcing it into close sealing contact with the u per edge of the bottle. Cork the material best suited for seals of this character, varies in density and quality, and where the quality is poor or the cork is soft, or the sealing pressure varies in different machines, exceeding that necessary to make a perfect seal, the cork is sometimes out through by the upper edge of the bottle. This causes theseal to leak, either immediately upon or soon after application. In applying seals wherein the cork or sealing disk is exceptionally hard or dense, and the sealing pressure in a given machine uniform, the full sealing pressure being placed upon the cork, the reaction after sealin is through the cork. This-reaction causes the flange of the cap in looking it on the bottle, to sometimes take hold too high up or too near the medial line of the bead on the bottle, or that portion at which its diameter is greatest. In such instances a strong lockis not effected,,and the ap not having a firm hold upon the locking surface of the bead,.leaks or is blown ofl with comparative ease in the steaming process.

The object of this method of applying to bottles, caps containing a compressible sealfor aping member, is to apply in the sealing operation, sufficient pressure upon the cork disk to effect a perfect seal, and when this seal between the sealing member and the bottle is effected, the further pressure exerted upon the cap being mainly taken upby the flange of the cap prevents cutting of the sealing I member, and at the same time an auxiliary seal between the metal of the cap and the bead upon the bottle, is formed at a point adjacent to the edge of the sealing member.

v The various steps of applying the seal or closure in accordance w th my method,

are shown in the accompanying drawing, wherein:

Figure 1 is a sectional view of the upper portion of the bottle, the cap in juxtaposition thereto as when assembled in the first step.

Fig. 2, is a similar view showing the flange of the cap slightly expanded as when being forced upon the bottle. Fig. 3, is a view showing the cap at that point where the sealing member is about to be crowded to a sharp edge between the interior surface of the flan e and the upper portion of the head of the ottle. Fig. 4, is a view showing the cap u on the bottle just before the lower portlon 0 its flange is crimped, pinched or fold ed into engagement with the under surface of the bead upon the bottle. view showing the seal applied and locked,

Fig. 5, is a sectional and Fi 6 is a side elevation showing the seal applied.

The numeral 1 designates a bottle of ordinary construction such as that to which seals known as Crown seals are applied, or a bottle having an annular laterally extending bead 2, adjacent to its mouth, whichverges into the upper edge of the bottle.

The lower portion the bead, below its medial line forms a locking surface 3, against which the flange of the cap is pinched, crimped or-folded, to lock the cap.

The cap is designated by the numeral 4 formed with a flatupper portion 5, rounded In practicing my method, the cap containing the sealing member, and bottle are manually or otherwise assembled as shown in Fig. 1. Pressure is applied which acts to expand the flange and during the downward movement of the cap or the upward movement of the bottle, as the case may be, the compressible sealing member or cork disk is brought into engagement with the upper edge of the bottle. Further movement further expands the flange and compresses the sealing member as shown in Figs. 3 and 4,

and additional pressure Will then and finally operate to bring the flange of the cap forcefully into engagement With the bead upon the bottle at a point adjacent to the edge of the-sealing member, and after the full pressure'has been applied, the lower edge of the flange is pinched, crimped, or folded into lockin engagement with the locking surface of the ead.

B this method of applying bottle caps it has een found that the cutting of the cork is rendered absolutely impossible, and in addition to this an auxiliary seal is formed between the cap and the bead upon the bottle,

sealing member.

Claim. The herein describedmethod of applying to a bottle having an annular external bead adjacent to its mouth, a hardmetal cap having and the upper edgeof the bottle, and also an auxiliary seal between the metal of the cap and the bead on the bottle, adjacent'to the edge of the sealing member whereby the pressure exerted upon the cap is mainly' taken up by the flange of the cap, prevents the cutting of the sealing member, and finally forcing the flangeof the cap or aportion thereof into locking engagement with the bead on the bottle below the medial line of said bead. In testimony whereof I aflix my signature in presence of'two witnesses.
